Some friends show up in your life with love and laughter… and some show up in your life and at the scene of the accident!Huge shoutout and heartfelt thank you to my dear friend Mark Cornelius — aka Lawyer Mac — for being both a cherished friend and an incredible advocate. When I needed someone most, he was my first call… and true to form, he answered the phone with, “Did you have an accident?” (He already knew!)From that moment on, Mark offered sound advice, handled every detail with precision, followed up consistently, and helped me reach a quick and fair resolution. Today, I picked up my settlement check — and I couldn’t be more grateful.Thank you, Mark, for being the kind of friend who shows up and the kind of lawyer who gets it DONE. I appreciate you more than you know!#Grateful #LawyerMac #FriendshipAndJustice #ThankYou #HandledWithCare

I cannot recommend Mark Cornelious highly enough! Over the years, he has helped me and my family on several occasions, and his expertise and dedication have been invaluable. There was one instance where he offered to step in at the last minute for a court appearance, and I was blown away by how well-prepared he was. He knew exactly what questions to ask and how to approach the case, which ultimately led to a successful outcome. His professionalism, thoroughness, and commitment to our case made all the difference. If you need a lawyer who truly knows their stuff and cares about their clients, Mark is the one to go to!

I would highly recommend Mark A Cornelius. He was easy to work with, he communicated with me frequently and was always willing to answer any questions that I had. He and his staff were a pleasure to work with.

I'm so grateful for Mark! I was in a car accident two years ago that totaled my car and caused a herniated disc. I had to go to physical therapy, and the other parties' insurance company had called me and sneakily got me to agree to accept them sending me some money to my bank account without me signing anything or disclosing that it was a settlement. I tried going to Dan Newlin and once they saw I had accepted money from the insurance company, they told me there was nothing they could do for me.I met Mark by chance and he told me about a client of his that he helped that sounded similar to my situation, and so I shared my story with him, and he told me that there was still a chance for me to get something. Sure enough, he was able to give me my settlement within a couple of weeks and put some extra money in my pocket that I would have never seen because other lawyers didn't even want to try. Thank you Mark!

Mark is the best lawyer I’ve ever had. He fully took control after my accident and didn’t give up on me or my case he won my case. He stays in contact with you every step of the way communication is the key to a great lawyer. Thanks again Mark for everything you and your assistant Patrice are the best.

I would highly recommend Mark for any and all injury attorney needs. He is extremely kind and explains everything in the process. He answered all my questions and concerns without making me feel incompetent or an inconvenience. After meeting with multiple attorneys, we met Mark and knew instantly that he was by far the best choice for our accident. He has truly gone above and beyond in every way. His staff is equally as incredible as he is and brings an exceptionally communicative, professional, and respectful environment during a difficult and stressful time.
